JD,
Real close. Try:
Thisform.txt3.Value = thisform.c11.value * thisform.c21.value

The 2nd (bound) column is stored in the Value property.

>basically, when a boardsize is chosen, i want to use the multiplier in column 2 to be used in mathematical functions. for example, if 2x4 is chosen, then 196 would be placed in the math function. what i'm getting now is a multiplier of 2. i can see why, but how do i avoid the problem?
